I have wanted to be a veterinarian for as long as I can remember. Even before I can remember, my Mom tells me that I wandered towards any dog I saw at the park. I was always sneaking lizards, baby birds, and the occasional stray kitten home, and trying to "save" them. This goes much better since veterinary school.
Having also studied James Herriot's novels (must reads if you haven't yet), I knew practicing veterinary medicine would provide me with daily variety, challenge me to continually learn, and allow me to meet interesting people and animal personalities. I love hearing stories about my patient's adventures/misadventures. I find it most rewarding helping them live long happy lives so that they have more stories to tell!
